Jack Brabham's grandson, Matt, to contest Indianapolis 500

The grandson of Australian motorsport legend Sir Jack Brabham will race in next year's 100th Indianapolis 500.

The 21-year-old is just the third third-generation driver to qualify for the 500, following in the footsteps of his grandfather, who drove the first rear-engined car in the race in 1961, and father Geoff, who had a best finish of fourth from his 10 starts in the 1980s and 90s.
